As answered by people managing Elfsight and DocSpring.
DocSpring's answer:
One API covers PDF forms, Word documents, page designs and HTML templates, with the same JSON and the same e-signatures, so you don't need a second tool when a customer sends you a Word contract. Templates have typed fields and validation that catch bad data before a document is made. Test PDFs are free and unlimited, and the free plan has no time limit.
DocSpring's answer:
Developers and product teams who build documents into their software: loan, insurance and rental applications, patient intake and consent forms, tax and government forms, contracts, invoices and certificates. That includes SaaS companies whose own customers set up templates in DocSpring's embedded editor.
DocSpring's answer:
I used to work at a payroll company (Gusto). We had built a similar in-house tool for filling out tax forms. I then built the first version of DocSpring (formerly named FormAPI) while I was living in Thailand. I built it to automate the filling out of visa application and visa extension forms, but realized that it could also be used for tax forms, real estate contracts, and any other kind of fillable PDF form.

DocSpring's answer:
DocSpring fills every kind of document from one API: PDF forms, Word documents, page designs and HTML templates. AI sets up the fields on any PDF, fillable or flat. The same template gives you a web form and e-signatures, and your customers can set up their own templates in our editor, embedded in your app. Your AI assistant can do all of this too, through our MCP server. DocSpring is SOC 2 Type II audited and HIPAA compliant, with US or EU hosting.
